HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 615,211, dated November29, 1898.

Application filed May 23, 1398. Serial No. 681,528. (No model.)

To all 1071,0111, it may concern.-

Be it known that I, JAMES P. CALL, a citizen of the United States,residing at Redondo, in the county of Los Angeles, State of California,have invented a new and useful Improvementin Hyd rocarbon-Burners, ofwhich the following is a specification.

My invention relates to improvements in hydrocarbon-burners in whichhydrocarbon fluid in the presence of steam is injected into the furnaceto form a fuel; and it consists in the novel method in which the steamand fluid are injected into the furnace and in the novel manner in whichthe burner is constructed.

The objects of my invention are to provide a burner of simpleconstruction which will feed the oil into the furnace immediately belowthe steam-outlet and to utilize the suction created by the discharge ofthe steam to draw the oil up and out of the oil-discharge port and atthe same time to provide a burner in which the different parts may bereadily cleaned without removing the burner from the furnace. Iaccomplish these objects by the mechanism described herein andillustrated in the accompanying drawings, in which- Figure 1 is a sideview of my burner. Fig. 2 is a top view of the oil-discharge chamber.

A is the steam-pipe connected to a boiler and having mounted thereon theusual steamcontrollingvalves. (Notshown.) Thispipe is located above theoil-pipe B and has cut in the end which projects into the furnace thehorizontal steam-discharge slot I. Attached to the oil-pipe B is theoil-discharge chamber D. Forming a part of the top of this chamber is aplate D, adj nstably attached by means of the bolts E, its front endconforming to the shape of the chamber D, which at this point iscircular. The opening between the end of the plate D and the casing ofthe chamber D forms the oil-outlet F. The size of this outlet can beregulated by means of the bolts E. This is rendered necessary on accountof the different consistency of diffen ent oils. The oil and steam pipesare connected by the pipe H, having cut-0E valve L, thereby affordingmeans to pass steam through the oil-pipe and oil-discharge chamber toclean the same. The brace M connects the ends of the oil and steampipes.

The plugs K, which are screwed into the fittings on both the oil andsteam pipes, enable the operator by unscrewing them to removeobstructions that may lodge in the nozzles without removing the burnerfrom the furnace. The steam-outlet I is semicircular in longitudinalsection and conforms in shape to the oil-outlet F, being disposed aboveand slightly in the rear of the oil-outlet.

I have found by careful experiments ex: tending over many months thatburners of this class are very sensitive and that slight changes inrelation to size and location of parts will almost destroy theefficiency of a burner. I have used a burner of a size adapted for usein a furnace having a capacity for steam production forengines of fromthirty to one hundred nominal horse power and which has givensatisfaction. It is constructed from one-fourth-inch pipe. Thesteamnozzle A has a discharge-slotone-sixteenth of an inch in width. Theoildischarge chamber is one inch wide, with walls one-eighth of an inchthick. The discharge opening F when at its minimum capacity, as shown inFig. 2, is one-eighth of an inch in width. The dotted lines, Fig. 2,show how the opening maybe enlarged by the adjustment of the plate D.The top of the oil-discharge chamber D is parallel with and one-fourthof an inch below the slot I, which is immediately above and slightly inthe rear of the oil-discharge outlet. When different-sized burners areconstructed, these proportions should be observed.

In all burners with which I am acquainted in which the oil and steam areinjected into the furnace separately the oil is fed into the furnaceabove the steam. In my burner it is fed below. -I find by experimentthat this produces better results, as but little, if any, residuum isdeposited in the oil-discharge outlet. My burner is operated in theusual manner.

Having thus described my invention, what I claim as new is- 1. Ahydrocarbon-burner composed of a steam-pipe, having a nozzle with ahorizontal slot, adapted to discharge the steam horizontally over andacross the oil-discharge outlet, and an oil-pipe having an oil-chamberlocated under the nozzle of the steam-pipe, having an adjustabledischarge-opening; the oil-chamber having, at its minimum capacity, asemicircular opening adapted to discharge the oil upward immediately infront of and just below the steam-nozzle, substantially as shown anddescribed.

2. The herein described hydrocarbonburner, comprising the steam-supplypipe, A, and oil-supply pipe, B, the steam-pipe, A, having nozzle, A,with steam-discharge port, I, and the oil-supply pipe, B, with theoil-discharge chamber, D, the oil-discharge chamber, D, havingadjustable plate, D, mounted in the top of said chamber, and theadjustable plate, D, substantially as shown and described.

3. A hydrocarbon-burner for furnaces having a semicircular steam-nozzle,I, at the end of the steam-supply pipe, A, and an oil-discharge chamber,D, at the end of the oil-supply pipe, B, the chamber, D, having theinner side of the front face semicircular, and the adjustable plate, Dsemicircular on its front end, to conform in shape with the inner sideof the front face of the chamber, the intermediate space forming theoil-discharge port, F, located substantially as shown and described.

4-. In a hydrocarbon-burner, provided with a steam-feed pipe, A,projecting horizontally into the furnace, and terminating with asemicircular steam-outlet, I, and an oil-feed pipe,

B, disposed immediately below the pipe, A, and terminating in anoil-discharge chamber, D, the oil-discharge chamber, D, semicircular onthe inner side of its front face, to conform in shape with the front endof the adjustable plate, D, and the adjustable plate, D, beingsemicircular at its front end and secured in position by nuts, E,substantially as shown and described.

5. In a l1ydrocarbon-burner, having oil and steam supply pipes withtheir regulatingvalves, the discharge-chamber, D, having adjustableplate, D, the front end of which is semicircular, disposed immediatelybelow and slightly in advance of the steam-discharge outlet, and soarranged that the oil-discharge outlet afforded by the semicircularopening intermediate the front end of plate, D, and that part ofchamber, D, immediately in front thereof will be below and slightlyinadvance of the steam-outlet and steam-pipe A, having nozzle A withsteam-discharge port I, Whereby steam ejected from the outlet, I, willpass over and mingle withoil ejected from the oiloutlet, F,substantially as shown and described herein.
